The objective of this study is to determine whether early radiofrequency (RF) ablation
treatment, using the CARTO® 3 or CARTO® XP System, and THERMOCOOL® Catheter Family (including
THERMOCOOL® SF or THERMOCOOL® SMARTTOUCH™) in subjects with paroxysmal atrial fibrillation
(PAF), delays progression of atrial fibrillation (AF) compared with drug therapy (either rate
or rhythm control) using current AF management guidelines.
